Patent FR-2581433-A1 (FR)
Title: Gearbox device with a string of balls
Inventor: ORSA MICHEL D
IPC: F16H3/36
Filed: 1985-05-03
Abstract: The invention relates to a gearbox, whose principle resides in the make up and use of a variable ratio gearing, this gearing being produced by two matched conical components 1 and 2 between which a string of balls passes. In order to allow the transmission of power without sliding, the surface of the conical components is hollowed with hemispherical cavities in which the balls of the string take position as shown in the figure. The cavities are distributed in circles or rows towards which the balls of the string are guided. When it is desired to change the speed ratio between the two cones the guide system causes the string to pass from one row of cavities to the adjacent one. The start of this change of row is synchronised so that the first ball in the new row is positioned in a cavity which arrives facing another cavity of the corresponding row. This synchronisation is done from an electric signal supplied by electro-optical detectors (photodiodes) which can only receive light coming from light-emitting diodes when the cavities of the two cones are face-to-face at the desired moment.

Patent FR-2586730-A1 (FR)
IPC: E04B1/10
Filed: 1985-09-02
Abstract: The invention relates to creation and utilization of a nailable or screwable section, the design and fixation of prefabricated panels with wooden framework, and the insulation by parietodynamics of gaps of air circulating in the walls and floors of said houses. The bottom girder fixed to the nailable section embedded in the concrete runs as a tenon under the downstair panels which are made integral therewith. The undeformability of the frames provided by nailing and glueing of facings which admit high distortion stresses enables the panels to perfect the windbracing. The thicknesses of the panels are flanged by dowelling with a maximum rigidity. The mineral insulation is provided between two vertical air gaps having each an orifice of at least 33 cm<2> per meter of width. The reflection of the convection of said air gaps on a system of caps limits the calorific exchanges through the walls.
